Google is still accepting applications up to March 13 for Open Source projects wanting to be mentoring organizations for the Summer of Code 2009. Student applications then open officially on March 23.

As Leslie Hawthorn of Google's Open Source team writes in a blog, Google is soliciting organizations to be mentors to students in their Summer of Code (SoC) 2009 program. The program provides funding for developers that implement particularly compelling ideas in open source projects.

Projects can apply to become mentors up to March 13. Students can then begin applying as of March 23. Google will publish the list of mentor organizations on March 18.

By Google's claims more than 2,500 students have successfully participated in the program over the last four years, paired with an equal number of mentors. The program will take place over a three-month period. More than five million lines of source code have been produced and the SoC has grown to be a virtual institution in open source circles. Details about the program are available here as an FAQ and in the #gsoc channel on Freenode.
